"JT Dunn Climate Control won my business by being honest and letting me know what would be in my best interest on the maintenance of two HVAC systems in an industrial building of mine. They were very thorough and saved me a lot of money. Then as part of a renovation project they removed two older systems and replaced them with one, installed four new gas infrared heaters on the dock, repaired an old heater, removed other old equipment, and repaired ductwork. They were excellent in every way. They are reliable and trustworthy. They are definitely going to maintain my systems going forward. And they are now the first HVAC company on my list for any project. Next, I'm going to ask them to quote the replacement of my 18-year-old home HVAC system."

"Sam Marsala was very good at diagnosing my furnace trouble, the fix was simple to my relief. My water heater was on its last legs. Sam diagnosed the trouble and we had Sam install a new Raheem water heater. He was very quick to respond to my needs and explained very clearly the trouble found. Installation was really done neatly and he left the work area very clean. I am more then satisfied with the work, product and technician. Well done."

"Jacob and Cody have been amazing to work with. We originally hired them to repair our stairs and have since contracted with them to install our kitchen tile floor, install electric in our kitchen island and to repair some of our drywall. Their team is very professional, their estimates are accurate and they do quality work. We plan to hire them again when we remodel our bathrooms."

"The boiler was fairly new, but had never been serviced. The workman came on Saturday in response to an emergency call, and fixed the boiler as well as performed basic maintenance which badly needed to be done. He didn't bleed the radiators, so I will be contacting the company to make arrangements to have that techs do this as well. I would consider relying on Vitt's for routine maintenance of our heating system, as well as replacement of our water heater."

"While performing two small repair jobs, they discovered a much more serious problem, a pipe leaking into the basement, which had been going on unnoticed for a long time. They were able to return the following day and make the repair. I was extremely impressed with their professionalism, the quality of their work, and their pleasant dispositions. The jobs were done quickly and the cleanup was thorough. I will absolutely call Mayo Plumbing again if I have a problem, small or large."

"We had Jones Air & Water come out to install filtration and replace a catalytic core system that we had installed to prevent descaling. In our situation, we had a high volume of Chlorine in the water that you could definitely smell and taste. The catalytic core system, didn't live up to the expectations and we still had to deal with a heavy scale build up noticeable on all of our faucets and with two Rinnai units for on demand hot water that raised concerns about what type of build up we were having on what we couldn't see. Everett came out and was very thorough in testing the water and then explaining a recommended solution. We finally decided on a dual media tank solution that Everett and JD installed that provides us with an efficient way to not only handle the Chlorine issue, but truly conditions the water and we're noticing all of the differences that Everett explained we should see. We are very satisfied with the whole process from the review of what our situation is, the recommended solution, the installation and the end result. We highly recommend using Everett for a water treatment solution."

"Froggy's called me immediately after I submitted my request on Angi. We discussed the problem I was having, and they gave me several ideas to try to get my A/C unit running properly before actually coming to take a look. I ended up taking their suggestions - cleaning the unit and blowing out the drain line - which resolved the issue. I appreciate and respect a company willing to provide a few troubleshooting/DIY tips before being eager to charge a service fee. Will definitely call in the event I need help in the future."

"Excellent service by professionally trained and licensed serviceman. They kept in contact with me during the day when to expect the serviceman and once here, completed the job in under an hour including explaining how the new thermostat worked and how to program it. They are on my Call List for future needs and I highly recommend them."

FAQs for water heater repair or service projects in Barnhart, MO

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
